Every morning, a bakery makes wheat bread. The staff bakes 20 loaves before the bakery opens at 7am and then bakes 10 more loaves every half-hour for the next three hours. If the number of loaves they have finished baking depends on the number of hours that have passed since the bakery opened, what is the range of this relation?

range:{20, 30, 40, 50, 60, 70, 80}

Explanation:

The range represents all possible values for the dependent variable, y. In this relation, the dependent variable is the number of loaves the bakers have finished baking.

At opening, they’ve already finished baking 20 loaves. Each half-hour after that, they finish baking an additional 10 loaves.
